A circular corrugated metal pipe culvert (n = 0.024) is 30.0 m (98.4 ft) long and 1.22 m (4.0 ft) in diameter. The culvert has a projecting pipe entrance (Ken = 0.8) and a free jet outlet. Compute the slope of the culvert so that the discharge for exit control is just equal to that for inlet control. Base the computations on a headwater depth (H) 4.0 m (13.1 ft) and an orifice coefficient (CQ) of 0.62.
